因要考虑到两个环境：公司电脑和家里电脑
所以环境有点特殊：虚拟机和虚拟机上的docker不能拷走。
| 环境 | 配置 |
|---|---|
| centos | root/root,配置host为:www.springbootvuestudy.comcomcom |
| mysql | root 123456 |
| redis | 123@456 |
| redis cluster | 8001~8008 |
mysql Docker 上安装、启动 MySQL （图解）
docker search mysql
docker pull mysql
docker run -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci --lower_case_table_names=1
# mkdir -p ~/mysql/data ~/mysql/logs ~/mysql/conf
# docker run -p 3306:3306 --name mysql -v $PWD/mysql/conf/my.cnf:/etc/mysql/my.cnf -v $PWD/mysql/logs:/logs -v $PWD/mysql/data:/mysql_data -e MYSQL_ROOT_PASSWORD=123456 -d mysql --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
docker exec -it mysql bash
docker pull redis
#docker run -d -p 6379:6379 --name redis redis
docker run --name redis -p 6379:6379 -d redis --requirepass "123@456"
docker exec -it redis bash极简 docker 环境 redis 5 安装 redis-cluster 集群（不需要Ruby）
# 下载ruby的镜像，作为redis cluster镜像的基础
docker pull ruby
# 更正 docker pull ruby:2.5
docker pull ruby:2.5
# 创建redis cluster容器的配置文件
mkdir /home/redis-cluster
cd /home/redis-cluster
touch redis-cluster.tmpl
vi redis-cluster.tmpl
cat /home/redis-cluster/redis-cluster.tmpl
# 创建自定义的network
docker network create redis-net
# 在/home/redis-cluster下生成conf和data目标，并生成配置信息
for port in `seq 8001 8008`; do \
mkdir -p ./${port}/conf \
&& PORT=${port} envsubst < ./redis-cluster.tmpl > ./${port}/conf/redis.conf \

WARNING: redis-trib.rb is not longer available!
You should use redis-cli instead.
All commands and features belonging to redis-trib.rb have been moved
to redis-cli.
In order to use them you should call redis-cli with the --cluster
option followed by the subcommand name, arguments and options.
Use the following syntax:
redis-cli --cluster SUBCOMMAND [ARGUMENTS] [OPTIONS]
Example:
redis-cli --cluster create 172.20.0.2:8001 172.20.0.3:8002 172.20.0.4:8003 172.20.0.5:8004 172.20.0.6:8005 172.20.0.7:8006 172.20.0.8:8007 172.20.0.9:8008 --cluster-replicas 1
